“After several difficult years for taxpayers, the IRS, and society in general, tax administration in 2023 mostly managed to leave its COVID-19 problems behind. The IRS eliminated most of its processing backlog, generally paid refunds timely, and answered taxpayer telephone calls at pre-pandemic levels. The good news is that, with limited exceptions, we are back to business as usual.

“The bad news is that the baseline level of ‘business as usual’ was not good enough. Our nation’s taxpayers deserve a 21st century tax administration agency that is fair and equitable, provides timely and clear guidance, makes it possible for all taxpayers to electronically file their tax returns, answers its phones and resolves most issues at the first point of contact, and allows taxpayers to conduct business on any follow-up matters through online accounts in the same way they conduct business with their financial institutions.”

Erin M. Collins, National Taxpayer Advocate

Most Serious Problems Encountered by Taxpayers

Each year’s Annual Report to Congress identifies the ten most serious problems facing taxpayers and offers recommendations to fix them. These issues can affect taxpayers’ basic rights and the ways they pay taxes or receive refunds, even if they’re not involved in a dispute with the IRS. As your Voice at the IRS, the National Taxpayer Advocate uses the Annual Report to elevate these problems and recommend solutions to Congress and the highest levels of the IRS. Additionally, TAS has a Most Serious Problems At a Glance document breaking down the ten most serious problems taxpayers faced this year and related key statistics.

About the Report

The Taxpayer Advocate Service (TAS) is an independent organization within the IRS. Led by the National Taxpayer Advocate, TAS is your Voice at the IRS.

The National Taxpayer Advocate’s Annual Report to Congress identifies taxpayers’ problems and provides suggestions to further protect taxpayer rights and ease taxpayer burden.

The National Taxpayer Advocate delivers this report directly to the tax-writing committees in Congress (the House Committee on Ways and Means and the Senate Committee on Finance), with no prior review by the IRS Commissioner, the Secretary of the Treasury, or the Office of Management and Budget.
